إعداد المصادقة

عند استخدام مكتبات البرامج، يمكنك استخدام بيانات الاعتماد التلقائية للتطبيق (ADC) للمصادقة. للحصول على معلومات عن إعداد "بيانات اعتماد التطبيق التلقائية"، يُرجى الاطّلاع على مقالة تقديم بيانات اعتماد "بيانات اعتماد التطبيق التلقائية". للحصول على معلومات عن استخدام ADC مع مكتبات العملاء، يُرجى الاطّلاع على المصادقة باستخدام مكتبات البرامج.
